Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a double-headed toothpick that allows easy cleaning of the interdental space from both the front and back sides.

[Conventional technology]

Conventionally, toothpicks are generally known as toothpicks made of a suitable wooden material with one end shaped into a sharp point. Various types of bending or bending at appropriate angles have been devised (Utility Model Application No. 55-636, Utility Model Application No. 56-68515, Utility Model Application No. 57-
(See Publication No. 126213).

[Problem that the invention aims to solve]

In general, it is not aesthetically pleasing to use toothpicks to remove and clean debris and plaque stuck between the teeth after eating in public, so the function of toothpicks is to:
The cleaning operation was required to be as small as possible and to be able to quickly remove the residue.

However, among the two mentioned in the previous section, the former, that is, a regular toothpick, is suitable for cleaning between the teeth from the front side due to its shape, but in order to bring the tip into contact with the back surface of the interdental area, it is necessary to The user had to open the door wide, making it impossible to remove the residue sufficiently, and the user had the disadvantage that these actions were conspicuous in public, impairing the user's dignity. On the other hand, in the latter case, the tip has a certain angle, so when cleaning between the teeth from the back side, there is no need to open the mouth as wide as in the former case. If you do,
There were various problems that still need to be resolved, such as the fact that the toothpick had to be operated while being held upside down in front of the mouth, and these movements were noticeable to those in the room.

The object of the present invention is to provide a toothpick that can reliably and easily remove debris from both the front and back sides between each tooth in the mouth with a simple operation.

[Means to solve the problem]

In order to achieve the above object, the double-headed toothpick in the present invention has a curved arm connected to one end of the handle,
A toothpick piece whose pointed end projects in the axial direction of the handle is attached to the base end of the arm, and a separate toothpick piece whose pointed end points toward the base end of the arm is removably attached to the tip side. It is.

[Effect]

The present double-headed toothpick according to the above-mentioned technical means uses the toothpick piece on the base end side of the arm to clean between teeth on the front side while holding the handle substantially horizontally. straddles the tooth row and can come into contact with the back surface of the interdental area at any time.

〔Example〕

Hereinafter, the structure of the present invention will be described in more detail according to the embodiment shown in the drawings. 1 is polyethylene, etc.
A handle 2 molded from a suitable synthetic resin is connected to one end of the handle, and holding holes 3' are provided at both ends.
3" is an arc-shaped arm formed by penetrating the arm, and 4 and 5 are toothpicks removably fitted into the holding holes 3' and 3" of the arm, both of which are commercially available. A wooden toothpick having been cut to a certain length from its tip is used, and the tip of the toothpick piece 4 shall protrude in the axial direction of the handle 2 from the holding hole 3' on the base end side of the arm, and the other A toothpick piece 5 is inserted into the holding hole 3”.
The pointed end of the arm 3 is oriented toward the base end side of the arm 3.

In addition, a toothpick piece 4 protrudes in the axial direction of the handle 2.
The angle between the toothpick piece 5 and the other toothpick piece 5 is preferably in the range of 130 degrees to 180 degrees.

Therefore, when using the double-headed toothpick of the present invention with the above configuration, the handle 2 is grasped with the fingers, and the arm 3 is placed in the oral cavity across the tooth row, and each toothpick piece 4,
5 to clean between the teeth on the front and back sides. At this time, the toothpick piece 4 on the base end side of the arm is used to clean the front side between the teeth, while the toothpick piece 5 on the arm tip side is used to clean the back surface between the teeth. This makes cleaning easier.

In addition, if the tips of the toothpick pieces 4 and 5 lose their sharpness due to use, a new toothpick piece is created by breaking a normal toothpick again, and this is inserted into each holding hole 3.
It is economically advantageous because it can be used repeatedly by simply replacing the used one within the range of '.3''.

On the other hand, FIG. 2 shows another embodiment of the double-headed toothpick of the present invention, which consists only of an arm 3 having a shape in which the handle 2 of the first embodiment is omitted, and a retaining hole 3' on the proximal end side of the arm 3. A normal toothpick 4a is passed through it as is, so that the toothpick piece 4 of the above example also serves as the handle 2, while a toothpick piece 5 cut short as in the above example is inserted into the holding hole 3'' at the tip end of the arm. It is fitted.

The double-headed toothpick having the structure of the second embodiment is more convenient in practice because a commercially available toothpick can be used as its handle. can be easily cleaned.

In addition, the double-headed toothpick of the present invention is as in each of the above embodiments.
The present invention is not limited to using commercially available toothpicks as the toothpick pieces 4 and 5, and even if each toothpick piece is integrally molded with the arm 3 and handle 2 from synthetic resin, this does not change the gist of the present invention. do not have.

[Effect of idea]

The double-headed toothpick according to the above structure has, in addition to the toothpick piece 4 on the proximal end side of the arm 3 extending in the axial direction of the handle, a toothpick piece 5 that straddles the tooth row via the arm and faces the back side. Since it is attached, the user can reliably and easily remove the residue not only from the front side between the teeth but also from the back side. Therefore, when cleaning the back surface of the interdental area in particular, there is no need to open the mouth wide or turn the toothpick upside down, unlike with conventional toothpicks, and the user can elegantly clean between the teeth in a nearly horizontal position. It is easy to handle, and even in public, there is no risk of the double-headed toothpick getting into the blind spot of the user's hand and spoiling their appearance. It has practical advantages.
